[Impact]
On some lenovo notebooks, ucm files are not loaded and mic can't be used

[Fix]
UCM was loaded based on cardlongname, but that can't cover all configs of the same model. Lenovo suggested to load  ucm by the first 3 letters of /sys/devices/virtual/dmi/id/bios_version, so that all configs could use just one ucm.

[Test Case]

[Regression Potential]

** Affects: alsa-lib (Ubuntu)
     Importance: Critical
